Adaptive transistors. So for those of you familiar with transistors, it sounds like what this is about is switching NPN transistors to PNP and vice-versa, and by doing this you can do such things as change a NAND gate in a circuit to a NOR gate. That's super nuts. I wouldn't think it'd be useful for anything, but they say, "Arithmetic operations, which previously required 160 transistors, are possible with 24 transistors due to this increased adaptability." And this boosts speed and energy efficiency. Only catch is you have to manufacture with germanium, not silicon.
